Introduction
Fluids must be considered as drugs, with serious adverse
effects and inconstant efficacy. Then, they should be administered only if
there is reasonable chance that cardiac output (CO) will increase in response.
Many tests or indices detecting “fluid responsiveness” have been developed for
this purpose.
With some of these tests, the relationship between CO and
cardiac preload is assessed through the haemodynamic effects of mechanical
ventilation. It is the case for the end-expiratory occlusion (EEO) test, which
has already been investigated in a reasonable number of studies [1,2,3,4,5,6,7,8,9,10,11,12,13]. In this commentary, we will explore
its haemodynamic effects, review the literature validating it and describe its
practical modalities.
